I'd like to offer my feedback about the battery thing.
After applying the OTA update (which we all know doesn't fix the reboot and battery drain issue) I have performed a factory reset.
Following that I had ZERO reboots.

Issues of note:
- Following the factory reset I was able to uninstall google+
- A new option appeared to disable services which cannot be uninstalled, like Asus My Zine.

So it might be that, and not the factory reset itself.

Regarding the battery:

- I have unplugged the Transformer exactly 5 hours ago. 100% battery charge, brought it to work, but didn't use it at all. Wifi was on though. In 5 hours i got 9% battery drain, which is absurd, especially comparing it with Honeycomb.

I have applied the fix specified in this thread, and I'll monitor the situation, and report back.
Thing is, if the reboot "fix" is permanent, that will save me some battery life, as having the tablet reboot itself and being stuck in a bootloop for a while ate a lot of battery. Regardless of that, ICS is a big disappointment in terms of battery life

Previous update (under 3.2); no deep sleep and battery drain. Took Asus weeks before they fixed it. Now with ICS update: same problem; no deep sleep and battery drain. Do they never learn?
Has anyone tried with CPU spy if their tablet go to deep sleep?

For those that still have power consumption issues: could you please try to disable "Backup my data"? It is found under Settings->Backup & Reset->Backup my data.

My battery drain issues were related with Google Trasport services always being on. There's probably an app that is incorrectly forcing a constant backup and, as such, not allowing wifi to turn off. I still did not figure which one it is, but at least now I battery consumption is less than 5% during the day when I'm not using it.

BTW, the app that allowed me to understand what was happening was "GO Power Master". You can also give "OS Monitor" a try.

Before trying this trick I tested my transformer and found it would not wake from the keyboard, only from the touchpad and touchpad buttons. I tried this fix and now it doesn't wake from touchpad either - I have to press the power button.

So it appears that the fix has worked!

Now I don't know if my battery drain issue is the same as the one the fix is for. I was finding that if my tablet and dock were connected, and the device was turned off, the device would still go flat in 3 or 4 days. Does anyone know if this trick will fix my power drain, or do I need to get my dock fixed?
